A progressive decline in cognitive function that interferes with daily activities, affecting memory, thinking, language, and judgment. It represents a group of symptoms rather than a single disease.
From Latin 'dementia' meaning 'madness' or 'being out of one's mind', from 'de-' (away from) + 'mens' (mind). The term has evolved from describing general madness to specific cognitive decline.
Dementia is like watching a magnificent library slowly lose its books, one by one! The brain's filing system becomes increasingly disorganized - first you can't find recent memories, then older ones start disappearing, until eventually even the most basic 'how-to' manuals for daily life become inaccessible.
